Warm engine no start - tfi already relocated

I had a bad problem with my truck stalling when it got warm. I relocated the tfi to the front of the truck on the driver side. Right where there is an opening to get plenty of airflow. My truck hasn't died on me since but it does not start when it is warm. Starts fine when it cools down. I thought remounting the tfi would fix this but I guess it hasn't. When it is warm/hot it does crank but fails to start. There is good fuel pressure. The other day when it wouldn't start I hooked a good spark plug on the wire coming from the coil. Cranked over and there is no spark. I felt the tfi and it was not warm. What can the culprit be? My guess is a bad coil. Previous owner said he replaced the coil though. What else can be wrong?
